Health. An entirely new way to use your health and ﬁtness information.

The new Health app gives you an easy-to-read dashboard of your health and ﬁtness data. And we’ve created a new tool for developers called HealthKit, which allows all the incredible health and ﬁtness apps to work together — and work harder — for you. It just might be the beginning of a health revolution.

“How are you?” now has a really accurate answer.

Heart rate, calories burned, blood sugar, cholesterol — your health and fitness apps are great at collecting all that data. The new Health app puts that data in one place, accessible with a tap, giving you a clear and current overview of your health. You can also create an emergency card with important health information — for example, your blood type or allergies — that’s available straight from your Lock screen.

See your whole health picture.

Quickly view your most recent health and fitness data in one dashboard.

Just in case.

Create an emergency card that’s accessible from your Lock screen.

Your health and ﬁtness apps will work even harder for you.

With HealthKit, developers can make their apps even more useful by allowing them to access your health data too. And you choose what you want shared. For example, you can allow the data from your blood pressure app to be automatically shared with your doctor. Or allow your nutrition app to tell your fitness apps how many calories you consume each day. When your health and fitness apps work together, they become more powerful. And you might too.

You are in charge of your data.

The Health app lets you keep all your health and fitness information in one place on your device and under your control. The information you generate about yourself is yours to use and share. You decide what information is placed in Health and which apps can access your data through the Health app. When your phone is locked with a passcode or Touch ID, all of your health and fitness data in the Health app is encrypted. You can back up data stored in the Health app to iCloud, where it is encrypted while in transit and at rest. Apps that access HealthKit are required to have a privacy policy, so be sure to review these policies before providing apps with access to your health and fitness data.
